An authentication information and a verification information are previously generated and the authentication information is stored to an authentication data generating apparatus, while the verification information is stored to a gateway. When a controller tries to make communication With a customer premises apparatus, the authentication data generating apparatus connected to the controller generates an authentication data using the authentication information and the gateway verifies the authentication data using the verification information. Moreover, the gateway restricts, when connected to the authentication data generating apparatus, the communication between the controller located in the outside of customer premises and the customer premises apparatus. Moreover, the gateway changes, while connected to the authentication data generating apparatus, an address of the customer premises apparatus and stores the changed address to the authentication data generating apparatus. The address of the customer premises apparatus is not informed to the controller provided in the outside of customer premises. Consequently, a system for safely controlling the customer premises apparatus from the outside of customer premises with the controller without bringing this controller into the customer premises to register a controller identification information to the gateway can be provided.

Communication using IPv6 is carried out, and conversion is given to a prefix of an IPv6 address in a firewall. A security channel for mutual authentication with an out-of-home apparatus or the like is carried out by the firewall, and only identification of an in-home apparatus is carried out on an in-home network by the firewall. A PC is connected to a PC in-home network different from the in-home network, and communication between the PC and the in-home apparatus is always carried out via the firewall.

Firewall apparatus

An information processing apparatus, such as might be associated with an in-home audio or video control device or a home appliance operated by a user, is provided with input allowing the user to set accuracy of a log of device operation history and/or to set a ratio of disclosure of the log information. A log accumulation control device efficiently collects the log information and offers users diversified levels of accuracy for the log information. In a further configuration, user-designated information acquired form user operation of the device identifies frequency of viewing and listening to each program, and reproduction of contents is controlled as a function of the user-designated information, e.g. to select among common contents and contents of different classification types.

In a system having two or more gateway apparatuses connected to both first and second networks having mutually different address systems, a gateway apparatus is provided with a translation table for associating IP addresses with node IDs. The gateway apparatus inquires other gateway apparatuses whether other gateway apparatuses are administering the same address as an IP address generated for a newly added device. If there is another gateway apparatus that is administering the same address, the IP address is prevented from being registered in the translation table.

An information processing system is configured such that which when an application handling multimedia, especially, moving images is performed by an information processor such as a personal computer, a sufficient processing performance is realized with the conventional CPU and bus capabilities. The information processing system includes a bus adaptor or bus converter for connecting a CPU bus and a system bus. The bus converter includes an operation processing unit (ALU) capable of performing a portion of an operating function performed by the conventional CPU or a portion of an operating function performed by an image processing board connected to the system bus, whereby the bus converter takes over a portion of a processing to be performed by the CPU or I/O module. Thereby, an overhead time for data transfer through the buses is reduced so that the total performance of the system is improved. Also, since a processing unqualified for the CPU, for example, a bit operation can be performed by a dedicated hardware, the information processing performance is improved.

A power supply section includes a capacity detector capable of detecting the remaining capacity in a battery and a controller issuing power consumption reduction instructions to independently operable function devices based on usage priorities thereof. This allows power consumption operations to be performed such as stopping function devices with low priorities first based on the remaining battery capacity. As a result, power to function devices with higher priorities can be maintained. Based on the remaining battery capacity, the controller controls the operations of the function devices and uses a display to show information allowing the operator to identify operable and inoperable function devices as the battery capacity drops.

Information processing device and method for controlling power consumption thereof

When conference conditions are set by a conference sponsor, a conference sponsor agent inquires of schedule management agents of requested attendants about available time within a range of set dates, determines an optimum conference schedule on the basis of the available time of the individual requested attendants, sends to the conference sponsor the conference schedule for confirmation thereof, and sends a conference notification to the requested attendants. In order to permit an input value set by a user to have a range in accordance with the kind of parameter requiring the input value and conditions at that time, an input value acquiring element acquires an input value of a parameter necessary for a processing realized by an application element, the input value being set by the user by an input element. An allowable value determining element determines an allowable value to be added to the input value on the basis of information supplied from the application element and corresponding to the kind of the parameter and conditions at that time, and an allowable value adding element determines a different input value from the acquired input value by adding the allowable value to the acquired input value and delivers the acquired input value and the thus determined different input value, as input values of the parameter, to the application element.
